The Plein boasts a military past. In the mid 17th century, a citadel was constructed here with barracks. In the middle of the military buildings was a training ground, the Plein. The military buildings were demolished, trees were planted and in 1879 the Plein became a public park. In 2002, it was renovated according to a design by the Wirtz agency. The rich canopied trees were felled and made room for arbours with paths made of dolomite. The fountains afford the park a vibrant touch. At the centre you will find a stage nestling between the grandstands. The monumental plane trees, linden and wild chestnuts are familiar features of the park.
